Overview of a three dimensional dose calculation system non coplanar planning system.
In the Radiological Clinic of Yassy we use our own therapy planning software based on the non coplanar photon beams system (TARGET SERIES 2 CGR GENERAL ELECTRIC). This program allows us to obtain the 3D perspectives necessary to accurately localize the target areas and their anatomic surroundings and the spatial interrelationship between the radiation beams, the external contour and the internal structures. Mean while the program determines the dose distribution in the tumour like 3D surfaces, the isodoses are displayed in user defined dose bands. One most useful features of this 3D planning system is the side view mode in which the images can be interactively manipulated and viewed along the central axis of the radiation beams. So the dose distribution is calculated and displayed in surfaces on planes with any orientation and position. In conclusion this program improve the speed of calculation and the efficiency of treatment planning.
